Inventor: KAWAMURA ARINORI
IPC: G02F1/1343
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To obtain a patterning method in which a transparent conductive film capable of obtaining a low specific resistance can be patterned with good fine-electrode workability by a method wherein the transparent conductive film is patterned by using an etchant composed of an acidic aqueous solution having an oxidation action to a metal which is used as the main component of a metal layer. SOLUTION: When a transparent conductive film is patterned, an etchant which is composed of an oxidizing agent whose oxidation-reduction potential of a metal layer 3 is noble and of an acid is used. Then, the concentration of the acid and that of the oxidizing agent, i.e., the pH and the oxidation- reduction potential of the etchant, are controlled properly, the etching rate of the metal layer and a transparent oxide layer whose etching rates are different intrinsically is balanced, the etching residue of the metal layer 3 is not generated, and the side etching operation of the transparent oxide layer can be reduced to a minimum.

Title: Liquid crystal display device
Inventor: UCHIUMI YUUKA
IPC: G02F1/1368
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To suppress optical leakage around a spacer in shade display or in the vicinity of the shade display by decreasing an electric field applied to a liquid crystal layer very near the surface of the spacer lower than an electric field determined by a voltage between electrodes formed on a substrate. SOLUTION: This liquid crystal display device holes a liquid crystal layer 54 between substrates 51, 52, which are laminated via a spacer 50 so as to form approximately a fixed thickness of the liquid crystal layer 54. Here, a dielectric constant of the spacer is made to be 1.2 times as high as an effective component of the dielectric constant or more, namely, the sum of those individual components in the direction of the electric field which are vertical and horizontal components of the dielectric constant of the liquid crystal material. And, when an electric field 9 is impressed on the liquid crystal layer 54 by electrodes 1, 4 formed on the substrate 52, the electric field 9 becomes close in the spacer 50 and becomes rough about the surface of the spacer 50.  Therefore, since the electric field 9 is weakened about the surface of the spacer, a threshold voltage increases apparently. Thus, an increase in an optical transmittance is suppressed and optical leakage around the spacer 50 is suppressed.

Title: Dephosphorization of molten metal
Inventor: MIZOGUCHI SHIYOUZOU
IPC: C21C1/02
Filed: 1981-03-12
Abstract: PURPOSE:To effectively dephosphorize molten metal (pig iron) without causing any damage to nozzle by molten metal by blowing a specific amount of CaCO3 as a dephosphorizer by oxygen gas from the nozzle. CONSTITUTION:In the dephosphorization of molten pig iron, powdered CaCO3 as a dephosphorizer is blown into the molten pig iron, together with oxygen as a carrier gas, through a dip nozzle. The amount of CaCO3 used is 10kg or more/ ton of molten pig iron and 40kg or less/kg of the P content of molten pig iron in the early period, and also the amount of oxygen as a carrier gas used is 1/9 or more of the amount of CaCO3 used. Thus, damage to the nozzle by molten pig iron can be prevented because the nozzle is cooled by endothermic reaction caused on the thermal decomposition of CaCO3 into CaO and CO2 in the molten pig iron, and also the dephosphorization reaction of the molten pig iron can be effectively advanced because P oxides can be effectively slagged by CaO following the oxidation of P by CO2.

Abstract: PURPOSE:To obtain a nonvolatile RAM whose information contents are not erased even when its source voltage drops or is cut off by using two nonvolatile semiconductor memory elements with floating gates for a bistable circuit and storing the information contents in the nonvolatile semiconductor memory elements. CONSTITUTION:Output information of the RAM are written in nonvolatile semiconductor memory elements Ma1 and Ma2 by holding VS at ''open'' and X1 at the ground potential, setting VCG to 15V, and varying VPP from 5V to 30V. The Ma2 is impressed with 30V at the drain and with 15V at the VCG to perform the writing operation. Consequently, the VT of the Ma2 is at -5V. On the other hand, the Ma1 has the drain held at 0V and VCG at 15V and its electric field is opposite in direction to the Ma2, so the VT of the Ma1 rises to +10V. Namely, erasing operation is performed. Thus, the writing and erasure are carried out at the same time. Then, the VPP and VS are raised from 0V to 5V to read the information back to the RAM. At this time, the VCG is set to 0V.
